The 50 Fastest Growing SaaS Companies (October 2026)

Venture money is pouring back into software, but it's piling up in a handful of names: a record $510 billion flowed into startups in the first half of 2026, and 43% of it went to just two AI labs, OpenAI and Anthropic.

For everyone else, you can't out-spend that kind of concentration. What you can do is build a product people come looking for by name.

So the question we set out to answer is: which software companies, across every category from dev tools to fintech to creative software to security, are actually growing demand right now?

These are the 25 software companies whose brand-name search demand has grown fastest over the past year, ranked from the steepest growth down, each with a trend chart, the key numbers, and a short read on what's driving the climb.

lemlist is a multichannel sales outreach platform that lets sales teams build prospect lists from a B2B database, verify contact details, and run personalized email and LinkedIn sequences at scale.

In late 2021, Expedition Growth Capital made a €30 million secondary investment in lemlist's parent company, Lempire.

lemlist is the fastest growing company on the whole list, which makes its trajectory worth paying attention to: +180% brand search growth means demand has nearly tripled in a single year. Cold outreach is a crowded category, but a wave of smaller sales teams looking for tools they can actually afford and operate without a dedicated ops person seems to be landing squarely on lemlist's doorstep.

Dental Intelligence Inc. is a practice analytics and performance platform built specifically for dental offices, giving practice owners visibility into scheduling, production, collections, and team performance in one place.

The company raised a Series A of $34 million in September 2019, led by K1 Investment Management.

Vertical SaaS for dental practices doesn't make many headlines, but +150% brand search growth suggests a real shift in awareness. Dental practice owners are a notoriously time-poor audience, and a platform that pulls together the numbers they care about, without requiring a dedicated analyst to interpret them, appears to be earning genuine word-of-mouth inside a tight-knit professional community.

Manychat is a chat marketing automation platform that lets businesses and creators automate conversations on Instagram, WhatsApp, Facebook Messenger, and Telegram to drive sales and bookings.

The company raised a $140M Series B in April 2025, led by Summit Partners, with Bessemer Venture Partners also participating.

Manychat is one of the bigger brands on the list by monthly brand searches, at around ~80K, which makes the +120% growth rate all the more remarkable: this isn't a tiny brand catching a first wave of awareness, it's a well-established platform that somehow doubled its search demand in a year. Instagram DM automation has gone from a nice-to-have to a core channel for e-commerce and creator businesses, and Manychat is the name most associated with that shift.

Topline Pro is a platform for home service businesses (plumbers, landscapers, contractors, and similar trades) that builds them an SEO-optimized website, syncs their listings, automates social media, and handles online payments.

The company has raised across three rounds: a $5M Seed led by Bonfire Ventures in 2022, a $12M Series A led by Forerunner Ventures in 2023, and a $27M Series B led by Northzone in August 2025.

Topline Pro has one of the lowest organic traffic footprints on the list, so the brand search growth is happening almost entirely through word-of-mouth and direct awareness rather than content. Home service businesses are a massive, underserved market, and when a plumber or landscaper finds a tool that genuinely handles their online presence without requiring any technical skill, they tend to tell other people in the same trade.

Heptabase is a visual note-taking and knowledge management app, built around a whiteboard-style canvas that lets users map out ideas, research, and learning in a spatial way rather than in a linear hierarchy.

The company raised nearly $1.7M in seed funding from Y Combinator, HOF Capital, Kleiner Perkins, and Moving Capital in early 2022.

The personal knowledge management space is crowded, but Heptabase has carved out a niche by being genuinely opinionated about visual, spatial thinking rather than trying to be everything to everyone. The +90% brand search growth suggests a growing community of serious learners (students, researchers, writers) who found it and told others, which is how these tools tend to spread.

ContactOut is a contact data platform used by recruiters and sales teams to find verified emails and phone numbers for professionals, primarily sourced via a LinkedIn Chrome extension and a standalone search portal.

ContactOut went through two accelerators, Startmate and 500 Startups.

ContactOut has been around for over a decade, but the +74% brand search growth signals that recruiter and sales demand for accurate contact data is accelerating rather than plateauing. With LinkedIn making third-party data access harder, tools that offer a reliable alternative are picking up users who need to get the job done.

Infisical is an open-source secrets management platform that helps engineering teams centralize and securely share environment variables and API keys across their infrastructure.

The company raised a $16M Series A in June 2025, led by Elad Gil, with Y Combinator and Gradient Ventures (Google) also participating.

Infisical is one of the youngest companies on the list, which makes consistent +61% brand search growth in a developer-native category all the more meaningful. Secrets sprawl is a real and growing problem for any team shipping software, and an open-source tool that engineers can self-host, inspect, and trust has a natural adoption path that paid-only alternatives don't.

CloudTalk is a cloud-based business calling platform aimed at sales and support teams, offering AI-powered call analytics, CRM integrations, and automated dialers for outbound calling.

The company raised a $28M Series B in January 2024, co-led by KPN Ventures and Lead Ventures, bringing its total disclosed funding to $36M.

Business phone software sounds like a solved problem, but as more sales teams ditch legacy telephony for cloud-native tools with real analytics baked in, CloudTalk is clearly picking up a meaningful share of that migration. The +61% brand search growth suggests that awareness is compounding, likely driven by reviews and peer recommendations inside sales operations circles.

Renderforest is an online branding and design platform that lets individuals and small businesses create videos, logos, mockups, and websites using template-based tools without needing design experience.

Funding is not publicly disclosed.

Renderforest is one of the highest-traffic sites on the list, with over a million organic visits a month, so the +60% brand search growth is happening on top of an already substantial audience. The template-based creative tools market keeps expanding as more small businesses need professional-looking content and don't have the budget for a designer, and Renderforest has quietly built a large user base in that space.

Flagright is an AI-native anti-money laundering compliance platform for fintechs and financial institutions, covering transaction monitoring, risk scoring, case management, and AML screening.

The company raised a $12.5M Series A in June 2026, led by Infinity Ventures, with Sella Direct Ventures, Frontline Ventures, and Y Combinator also participating.

Flagright is one of the smallest brands on the list by monthly search volume, sitting at around ~350 searches a month, so the +59% growth represents a genuinely small absolute number. That said, AML compliance software is sold to a very specific audience (compliance officers and fintech risk teams) where almost nobody stumbles onto a product by accident: a search for your brand name means someone has already heard about you from a peer or a conference, and that's a strong signal in a high-trust, high-stakes category.

Sumsub is a verification and compliance platform that handles KYC, KYB, transaction monitoring, and fraud prevention for fintechs, crypto platforms, gaming companies, and other regulated businesses.

The company raised a $30M Series B in December 2022, led by Flint Capital.

Identity verification is one of those categories where the regulatory environment does a lot of the selling: as more jurisdictions tighten KYC requirements, fintechs and crypto platforms need a reliable solution or they can't operate. Sumsub's +52% brand search growth suggests it's becoming the name compliance teams default to when they go looking, which in a category this compliance-driven is a durable advantage.

AppTweak is an app store optimization and intelligence platform used by mobile app marketers to improve organic and paid performance across the Apple App Store and Google Play.

The company raised a $22M Series B in April 2021, led by Groupe Rossel.

App store optimization has matured from a niche technical discipline into a standard line item in mobile marketing budgets, and AppTweak has grown alongside that shift. The +49% brand search growth, combined with a strong forecast, suggests that awareness is still expanding rather than leveling off, which is notable for a platform that's been around for over a decade.

Adalo is a no-code app builder that lets non-technical users create and publish functional web and mobile apps by dragging and dropping components, without writing any code.

The company raised an $8M Series A in May 2021, led by Tiger Global, bringing its total funding to $9.7M at the time. Participants included Wade Foster of Zapier and Jason Warner of GitHub.

The no-code market has become a lot more crowded since Adalo launched, but the +42% brand search growth suggests it's holding its audience rather than losing ground to newer entrants. For non-technical founders and small teams who need a real mobile app without the cost of a developer, Adalo's approachability keeps bringing people in.

NordLayer is a business network security platform built by the team behind NordVPN, offering companies secure remote access, zero-trust network access, and secure web gateway capabilities.

Funding is not publicly disclosed.

NordLayer benefits from a parent brand that most people already trust, but the +41% growth in its own brand searches suggests it's developing a distinct identity in the business security market rather than just trading on the NordVPN name. With remote and hybrid work keeping network security high on the list for IT teams at small and mid-sized companies, a tool that's easy to deploy and comes with a recognizable brand behind it is a natural fit.

Noloco is a no-code platform for building internal tools, letting operations and business teams create custom portals and dashboards on top of their existing data sources without developer involvement.

The company raised $1.4M in a pre-seed round in July 2022, with backing from Y Combinator, Sean Mulryan of Ballymore Group, Anamcara Capital, and a handful of other investors.

Noloco's +64% search growth forecast is the most optimistic on the list, and it comes against a backdrop of growing internal tooling demand as teams look for ways to build lightweight ops software without queuing up engineering work. For a small Dublin-based company with a modest organic footprint, the brand search growth is almost entirely word-of-mouth, which tends to mean the product is working for the people using it.

Favikon is an influencer marketing and analytics platform aimed at B2B brands and agencies, helping them find, rank, and manage creator partnerships across social platforms.

The company raised a seed round in December 2020, backed by Provence Business Angels.

B2B influencer marketing has gone from a fringe tactic to something serious marketing teams are actually budgeting for, and Favikon is positioned specifically for that corner of the market rather than trying to serve consumer brands and B2B brands simultaneously. The +36% brand search growth reflects a category that's still in the early stages of formalizing, with more teams going looking for a dedicated tool rather than trying to manage it in a spreadsheet.

beehiiv is a newsletter publishing and monetization platform built by former members of the Morning Brew team, designed for creators and media operators who want to grow and monetize an email audience.

The company raised a $33M Series B in April 2024, led by NEA, with Lightspeed Venture Partners and Sapphire Sport also participating.

beehiiv is one of the bigger brands on the list by monthly search volume, sitting at around ~30K searches a month, so a +35% growth rate on top of that base is genuinely substantial. The newsletter publishing category has consolidated around a handful of platforms, and beehiiv has become the go-to for creators who want more control over their business model than some of its rivals allow.

Oneleet is a cybersecurity compliance platform that helps companies achieve and maintain security frameworks like SOC 2, combining automated evidence collection with managed penetration testing.

The company raised a $33M Series A in October 2025, led by Dawn Capital, with Y Combinator, Frank Slootman, and Arash Ferdowsi among the participating investors.

Oneleet is one of the youngest companies on the list, founded in 2022, and security compliance is one of those categories where demand is partly driven by external pressure: startups need SOC 2 to close enterprise deals, so a wave of growth-stage companies entering that phase of their business creates a steady stream of first-time buyers going looking for a solution. Oneleet's +30% brand search growth suggests it's landing in more of those conversations.

EmailOctopus is a bootstrapped email marketing platform focused on simplicity and low cost, used by small businesses and individual creators who want to send campaigns without paying for features they don't need.

EmailOctopus is bootstrapped and has grown without external funding, as the company itself has stated publicly.

Email marketing is about as competitive a category as software gets, but EmailOctopus has found a durable audience among users who find the big platforms over-engineered and overpriced. The +30% brand search growth for a bootstrapped, London-based team that's been running for over a decade is a reminder that a clearly defined, affordable product serving a specific segment can keep compounding awareness long after the initial launch buzz fades.

Appcues is a no-code product adoption platform that lets product and growth teams build in-app onboarding flows, tooltips, announcements, and surveys without engineering support.

Product-led growth has moved from a buzzword to a real operating model for a lot of SaaS teams, and with it has come greater attention to the onboarding experience that makes or breaks early retention. Appcues has been in this category since before it had a name, and the +29% brand search growth suggests that as more teams prioritize activation and adoption, they're finding their way to a tool that's been solving this problem for over a decade.

Culture Amp is an employee experience platform used by HR and people teams at mid-size and enterprise companies to run engagement surveys, performance reviews, and leadership development programs.

Culture Amp is one of the most established companies on the list, founded in 2010, and it's been the platform of record for people-focused HR teams for years. The +26% brand search growth at this stage of maturity suggests the employee experience category itself is still expanding, with more HR leaders being held accountable for engagement and retention data in ways that weren't common even a few years ago.

Tipalti is a global accounts payable automation platform that handles supplier onboarding, invoice processing, tax compliance, and mass payments to vendors in multiple countries and currencies.

Tipalti is another of the most established companies on the list, also founded in 2010, and at ~20K monthly brand searches it's already a well-known name in the finance and accounts payable space. The +26% brand search growth for a platform of this size points to a broader acceleration in AP automation adoption, as finance teams at scaling companies realize that managing global supplier payments in spreadsheets stops working at some point.

Vacation Tracker is a leave management tool that integrates with Slack and Microsoft Teams to help small and mid-size teams track PTO, time off requests, and absence policies without a dedicated HR system.

Vacation Tracker is bootstrapped and has not raised any external funding.

Leave management is a narrow, practical category and Vacation Tracker has owned a clear position in it by building directly on top of the tools (Slack, Teams) where people already spend their workdays. The +24% brand search growth for a bootstrapped Montreal startup is steady, compounding momentum, the kind that tends to come from happy users recommending it to peers at similar-sized companies rather than from any particular marketing push.

OpenReplay is an open-source session replay tool aimed at developer and engineering teams who want to watch how users interact with their web apps in order to debug issues and understand behavior.

The company raised a $4.7M Seed round in June 2022, led by Runa Capital, with Expa, 468 Capital, and Rheingau Founders also participating.

OpenReplay is one of the smallest brands on the list by monthly search volume, at around ~400 searches a month, but it's sitting on top of ~210K monthly organic visits, which tells you it has a wide content and SEO footprint relative to its brand awareness. That's a healthy position for an open-source tool: lots of developers finding it through technical searches, and a growing share of them coming back to look for it specifically.

Awardco is an employee recognition and rewards platform that lets companies run peer recognition, milestone, and incentive programs, with points that employees can spend in a large marketplace of gift cards, products, and travel.

Awardco raised a $165M Series B in May 2025, led by Sixth Street Growth and Spectrum Equity, with General Catalyst and Qualtrics founder Ryan Smith also investing.

Recognition software is usually bought on peer recommendation, and HR teams that hear about a tool from another company tend to go looking for it by name. Awardco now counts AT&T, Adobe, and Hertz among its customers, and its brand searches have climbed to around 24K a month on the back of that word of mouth.

You can rebuild this entire analysis yourself in Ahrefs. Here's the short version:

What stands out across this list of fastest growing SaaS companies is how genuinely varied the categories are: dental practice analytics, secrets management, newsletter publishing, influencer marketing, leave tracking, and AML compliance all show up here, which is a useful reminder that brand demand growth is a product quality signal, not a sector trend.

The fastest growing companies on this list share one thing: they serve a specific audience well enough that those people go looking for them by name, often through word-of-mouth in tight professional communities, rather than because of a big advertising push.

If you're trying to understand where real software demand is forming right now, the brand search trajectory of companies like these is one of the cleaner signals worth tracking.
